Detailsinfo

A vulnerability was found in MongoDB Server up to 7.0.34/8.0.23/8.2.9/8.3.2. It has been rated as problematic. This issue affects an unknown part. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

An authorized user could trigger a server crash by running a query with a 2dsphere index on a field that stores a GeoJSON GeometryCollection containing a Polygon with a strict-winding CRS. Strict-winding polygons are intentionally unsupported for indexing, but the guard that rejects them does not inspect members of a GeometryCollection, allowing the unsafe path to be reached which ends with an ensuing null-pointer dereference.

The weakness was shared by muhammaddaffa. It is possible to read the advisory at jira.mongodb.org. The identification of this vulnerability is CVE-2026-9752 since 05/27/2026.
